A Study on the Air Flow Characteristic of Apartments According to Layout Form
Abstract:
In urban downtown, densely cluster building either as a large number of middle, low and high-rise, may experience various types of damage occurring around the buildings because of wind. Newly constructed apartment complexes fall to the risk of strong winds at the corners of apartment buildings or gusts on the pedestrian passages. Research is on pedestrians safety in connection to wind flow inside and outside apartment complexes constructed in downtown areas. This study selected 3 types of apartment complexes and compared the wind velocity ratio among different spots in the complexes through wind tunnel experiment and CFD analysis. Furthermore, we changed the deployment and outward form of apartment complexes through CFD analysis and examined the wind-velocity ratio reduction effect. According to the results of wind tunnel experiment, wind velocity between two buildings decreased usually, but wind velocity increased in the space between the sides of two buildings and the space between front and back apartment buildings. Again, when comparing the results of wind tunnel experiment with the results of CFD analysis, they showed similar tendencies except for wake areas. Etc.
